Gravimetric investigations of the development territory at Verkhnekamskiy potash salt deposit are undertaken in order to to reveal the details of geological structure, high dangerous sections and for examination of variations of density parameters of geological structure under the effect of mining works. Monitoring gravimetric observations increase sufficiently efficiency of investigations of density structure of salt and over-salt strata. Variations of gravity anomalies reflect dynamics of rock deformation processes and allow to predict of dangerous and catastrophic situations occurring during deposit operation. Rise of efficiency of gravimetric method of investigations is achieved via usage of high-precise equipment and up-to-date methods for interpretation of potential fields. The paper includes the examples of gravimetric investigations at the accident-potential mine sections. Geodynamical zones are emphasized according to gravimetric data, each of these zones has its own geological history of development and individual density structure. Joint analysis of transformants of gravitation field and its variations depending on time allowed to reveal areas of decompaction in over-salt stratum and to predict successfully collapse of the Earth surface at a flooded mine in the range of found chain of negative anomalies of gravitation field and dynamic anomaly.
